<h2>DESCRIPTION</h2>

<em>r.surf.gauss</em> produces a raster map of Gaussian deviates whose
mean and standard deviation can be expressed by the user. It uses a
Gaussian random number generator. It is essentially the same
as <em><a href="r.surf.random.html">r.surf.random</a></em>, but uses a
Gaussian random number generator instead.

<h2>EXAMPLE</h2>

<div class="code"><pre>
g.region -p n=228500 s=215000 w=630000 e=645000 res=10
r.surf.gauss out=gauss mean=0 sigma=10

# check result
r.univar gauss
</pre></div>

With the histogram tool the cell values versus count can be shown.
